SM24A-SR-TP - Belimo Damper actuator 20 Nm, 150 s, 95° AC / DC 24 V, modulating

At IACS we provide Free Delivery and Next 1-2 day Delivery for all the Belimo Actuators in stock.

The Belimo SM24A-SR-TP is an Actuator used in HVAC systems and applications to manage dampers.

This type of Actuator applies a Rotary motion to regulate the damper.

The Torque force applied by the SM24A-SR-TP is 20 Nm.

The power supply requested for this Rotary Actuator is 24Vac/Vdc.

If you have questions concerning size or installation, refer to the Belimo custom datasheet above or email iacs for individualised support.

Features
 

• Mode of operation  The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and travels to the position defined by the control signal. Measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.
  


• Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.
  


• Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).


• Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.
  
  
• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
